I'm using slush's pool with GUIminer and its not making bitcoins. Now, you might be saying I just have a slow computer. I'm using a xeon server with 12GB RAM and 12 cores 3.20gh each. Any help?
You've a slow computer!
Only bitcoin mining done now is asic mining.
Each GHz will give you around a KHz of power. There's only around 36KHs there then so you're not really going to get anything from that.
